EnterProtocolModeReply
This reply is the expected reply from transceiver module to the corresponding command
EnterProtocolMode.
EnterProtocolModeReply (reply)
Byte offset
Field
Description
0x00
Start-of-Packet
0xFB = Indicates start of protocol formatted message
0x01 - 0x02
Length
0x01 0x00 = Number of bytes in message following this byte (Little-Endian)
0x03
Packet Type
0x10 = EnterProtocolModeReply
DeviceReset
This resets the transceiver module (for local UART commands only, the transceiver will reply with
a DeviceResetReply message). This command can be wrapped as an air command.

0x00
Start-of-Packet
0xFB = Indicates start of protocol formatted message
0x01 - 0x02
Length
0x02 0x00 = Number of bytes in message following this byte (Little-Endian)
0x03
Packet Type
0x02 = DeviceReset
0x04
Reset Type
0x00 = Normal reset
DeviceResetReply
This is the reply message (only for local UART commands) after the transceiver receives a
DeviceReset command. An equivalent air command reply wrapped accordingly can be sent out from
a node back to its gateway if the latter sent an air command with DeviceReset as the wrapped
command.

TxLongData
Basic data send in command mode, that can span multiple consecutive broadcast phases. Note that
no reply is tied to this command. In the case where the transmitter is a gateway, then all nodes
directly or indirectly connected to that gateway via the mesh network that properly receives the
broadcasted packet will send a corresponding RxDataPacket reply to their own hosts. In the case
where the transmitter is a node, then only the gateway will send a corresponding RxDataPacket reply
at reception of packet. If another node needs to monitor that signal, then the proper sniffer
configuration register flags (RAM bank register sniffFlagsMask, flag BROADCASTIN_bm) must be
written (see section 7.3), in which case the corresponding sniffed receive replies to host will be in the
form of RXBcastInSniffedDataPacket.

Start Broadcast
Phase
0x00-0x03 = Start Broadcast Phase (range is in practice limited to B-1, where B is the
number of Broadcast Out Phases if sender is a gateway, or the number of Broadcast
